I Think We Have A Winner!

Searching for the Consumer Unit (fuse box) in a property today I opened a cupboard to find this antique. After the initial chuckle and "well it would have been that years ago" I carried on looking but couldn't find it.
Hang on, not way can this still be in use?
Can it?
Turns a couple of dials and the lights went out!!
"Err, I just need to get something from the van"
There can't be many setups like this still in use, or at least I hope not!!
